Question

Which of the following statement is true? 

A)The opposite sides of a trapezium are parallel

B)All the sides of a parallelogram are equal in length

C)The diagonals of a square are perpendicular to each other

D)All angles of a rectangle are not equal

​

Answer 1

Answer:

C)The diagonals of a square are perpendicular to each other

Answer 2

The statement, "The diagonals of a square are perpendicular to each other" is true.

• In a trapezium, only one pair of the two pairs of opposite sides are parallel. The other pair is non-parallel.
• Opposite sides of a parallelogram are equal in length, not all sides. If all the sides of a parallelogram become equal, then it would become a rhombus.
• The diagonals of a square form an angle of 90° with one another and are, therefore, perpendicular to each other.
• All angles of a rectangle are 90° and are hence, equal.
